Glue at parent nameservers
0/7

WARNING
The parent servers are not providing glue for all your nameservers. This means that they are supplying the NS records (host.example.com), but not supplying the A records.
That may cause some extra milliseconds in DNS. This will usually occur if your DNS servers are not in the same TLD as your domain

NS

Mismatched glue
7/7

Skip glue checking. Make sure the nameservers domain is good standing
Check ovh.net

SOA

SOA record

SOA record is:

Hostmaster email

tech.ovh.net

Serial

2018052901

Refresh

86400

Retry

3600

Expire

3600000

TTL

3600

Serial agreement
7/7

SUCCESS
All your nameservers agree that your SOA serial number is 2018052901 That means that all your nameservers are using the same data.

SOA MNAME
3/3

SUCCESS
SOA (Start of Authority) record states that your master (primary) name server is: dns106.ovh.net That server is listed at the parent servers, which is correct.

Serial value
1/1

SUCCESS
SOA serial number is: 2018052901 This appears to be in the recommended format of YYYYMMDDnn, where 'nn' is the revision. This number must be incremented every time you make a DNS change.

Refresh value
0/1

WARNING
SOA Retry interval is : 86400 seconds. This seems too big;. (Values about 3600-7200 seconds is good if not using DNS NOTIFY; RFC1912 2.2 recommends a value between 1200 to 43200 seconds (20 minutes to 12 hours)). This value determines how often secondary/slave nameservers check with the master for updates.

Retry value
1/1

SUCCESS
SOA Retry interval is : 3600 seconds. This seems OK. (Values about 120-7200 seconds is good). The retry value is the amount of time your secondary/slave nameservers will wait to contact the master nameserver again if the last attempt failed.

Expire value
0/1

WARNING
SOA Expire time is : 3600000 seconds. This seems too big;. (Values 604800 to 2419200 seconds (1-4 weeks) is good). RFC1912 suggests 2-4 weeks. This is how long a secondary/slave nameserver will wait before considering its DNS data stale if it can't reach the primary nameserver.

TTL value
1/1

SUCCESS
SOA Expire time is : 3600 seconds. This seems OK. (about 300 to 86400 seconds or 5 min - 24 hours is good). RFC2308 suggests a value of 1-3 hours. This value used to determine the default (technically, minimum) TTL (time-to-live) for DNS entries, but now is used for negative caching.
